But Bale is keeping his fingers crossed that the four-time Ballon d'Or winner will remain with the European champions.

Ronaldo's future at Real was brought into question when he made a shock revelation that he wanted to quit the club following accusations of tax evasion.

The 32-year-old, who had been linked with a return to Manchester United , has remained silent on his future since then and it remains to be seen if Real's all-time record goalscorer will line up for Zinedine Zidane's men at the start of the coming season.

Bale hopes that will be the case, but insists he has no inside knowledge as to what his team-mate - who last November signed a contract tying him to Real until 2021 - will end up doing.

Asked if he thinks Ronaldo wants to leave, Bale told Spanish newspaper Marca: "I've not read anything, I haven't got a clue about what's going to happen. Look, I only found out yesterday that (Romelu) Lukaku has signed for Manchester United... I honestly don't know.

"You'll have to ask him."

But on whether Bale wants Ronaldo to remain at the Bernabeu, the former Tottenham forward was much clearer, saying: "Of course, we won titles, we did well, we don't need to change anything."

Bale and Ronaldo have been club-mates since 2013 and were part of the Madrid squad that won the Champions League and La Liga titles last season, although the Wales international's contribution was once more disrupted by injury - including an ankle problem which almost robbed him of a place in the Champions League final in his home city of Cardiff.

The 28-year-old has been plagued by fitness problems during his time in Spain but is hoping a strong pre-season will help stand him in good stead for the coming campaign.

"(The ankle is) fine. Obviously during the holidays I haven't done a lot of intensive stuff on the area, in order to recover well," he said.

"I found it difficult to stay fit last season due to the pain. I've worked hard to recover and now be able to take a full part in pre-season.

"I was annoyed last season because you always try to return to help the team, and give the best of yourself. Maybe I should have had more time recovering, and not forcing things, but now there is no pain. The ankle feels strong and I'm ready.

"I'm going to try and have my best season, of course, and if I respect the injuries I will have a great season. Now I need to make myself strong to try and avoid these injuries."
